Crop your first image square, but frame it so a shopper can see the entire painting they would be purchasing without clicking on the listing.
Remove the photos where the painting is sideways on the screen.
Be much more clear about whether the paintings/prints will come framed or unframed, and what the associated price difference would be. This was confusing to me in a few listings, and I'd buy from someone else rather than reach out to you to clarify.
There is a cluttered background in a few of your photos, and in one I can see the reflection of blinds in the main part of the painting.
Try to make your shop feel like the online version of wandering through an art gallery.
I think your work is lovely, and that if you're able to display it to its best advantage you could be quite successful!
